The Ekman spiral is a term used in oceanography and meteorology to describe the spiraling pattern of ocean currents caused by wind, Coriolis force and friction. This phenomenon is also known as the Ekman effect or Ekman transport. Other synonyms for Ekman spiral include the Ekman layer, Ekman pumping, and Ekman convergence. The Ekman spiral plays an important role in the exchange of heat, salt, and nutrients between the ocean and atmosphere, as well as in the movement of marine organisms and pollutants. Understanding the intricacies of the Ekman spiral is crucial in predicting and mitigating the effects of climate change on the world's oceans.
